Application led'December 23, 1913.

T0 all 'whom t may concern y Be 1t known that l, GEORGE H. PIRsoN, a

citizen of the United States, residing at the art to which it appertainsto make and use the saine.

Myfinvention relates to new and useful improvements yin angle braces ofthat type designed particularly for bracing window screen frames or doorscreen frames or like structure whereby the life of the window or doorscreen is materially increased and sagging is prevented.

An important object of the invention is to provide an angle brace suchas above described that is adapted to be secured at several points atthe corners of awindow or door screen frame or like structure wherebythe frame is materially strengthened and not liable to .derangementowing to the manner in which the brace is secured at several pointsadjacent the joint of the frame.

Another object of importance is to providean angle brace such as abovedescribed which may be stamped out of a single blank of cheap metal, isreliable and ellicient in its purpose, cheap to manufacture andtherefore more commercially desirable than braces heretofore.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out in the claim whichis appended hereto and forms a part of this application.

1With reference to the drawings, wherein l have illustrated thepreferred embodiment of my invention as it is reduced to practice, andthroughout the several views of which, similar reference numeralsdesignate corre spending parts: Figurel is a side elevation illustratingthe device attached to the joint of a window screen. Fig. 2 is aperspective view illustrating the device attached to the joint of aframe, and Fig. 3 is a detail perspective view of the angle bracketremoved from the frame. i

Referring to the drawings forming a part of this specification and invwhich like numerals are employed to'designate corre- Specieation ofLetters Yatent.

spending parts, the numeral l designates as an entirety the anglebrace'of my improved construction that is adapted to be secured to thebars 2 and 3 of a window or door screen frame at the joint of the barsthereof. The angle brace l consists of a single blank of suitablemetallic material having an angular body portion 4. Formed along theshorter edges of the body portion 4 are a pair of integral securing sideand bottom flanges 5 and 6 respectively. These securing flanges 5 and 6are bent at right angles to the body portion -l and are each providedwith spaced apertures 7 through which suitable fastening means may beinserted to secure the device to the window or door screen frame. 'lhesecuring flange 5 is formed centrally of the straight side of the bodyportion 4 and is disposed at right anglesto the securing flange l5 whichis disposed centrally of the ends of ythe bottom edge of the bodyportion 4t. The securing lianges 5 and 6 are adapted for engagement withthe inner edges of the side bar 2 of the window or door screen and thebottom bar 3 of the frame as will be clearly seen with reference to`Fig. 2 in the drawn ings. The securing Hanges 5 and 6 after having beendisposed as above described are secured by suitable fastening means tothe side and bottom bars Zand 3 of the window or door screen frame.

Formed integral with the body portion l at the lower angular cornerthereof is an `outwardly and downwardly extending se curing tongue 8.This tongue 8 is disposed between the securing flanges 5 and (S andentends at right angles thereto. A pair of spaced apertures 9 are formedin the securing tongue 48 and are adapted to receive fastening meanswhereby the tongue is secured to the angular edges of the side bar and.bottom bar 3 of the window or door screen frame, as will be clearly seenwith reference to Fig. l in the drawings. lit will be apparent that theapertures 9 in the securing tongue S in being spaced provide for thesecuring of theI angular edges of the side bar 2 and bottom bar 3 thusstrengthening and reinforcing the frame 'to a great extent. l

A. securing tongue 10 is formed integral with the body portion lladjacent the upper end of the body portion, extends outwardly at rightangles to thesecuring flange 5, and is adapted for engagement with theface of y the side bar` 2. This securing tongue is apertured as is theother securing tongue so as to provide for the securing of it to theside bar 2.

A securing tongue 11 is formed integral with the body portion 4 adjacentone end of the bottom edge thereof vat right angles to the securingllange 6 which is `iisposed between the tongues l1 and 8 as will beclearly seen with reference to Fig. 3 in the drawings. This securingtongue 11 is apertured as are the other securing tongues and adapt- Iedfor engagement with the face of the lower bar or bottom bar 3 as will beclearly the bars 2 and 3, causing the bars to be brought into and heldin right angular relation, after which the tongues 8, l0 and 1lA aresecured to the outer sides of the bars. The flanges 5 and 6 insure thebars 2 and 3 being brought into proper relative position, and preventstrain from being thrown on the fastenings passing through the flangesand the tongues. The flanges also add strength and rigiditv to the body4. A portion of the body 4 extends from the tongue l0 to the tongue 1lat a point inwardly beyond the flanges and tongue 8. This portion of thebody forms a truss which is secured to the lbars 2 and 3 by the tongues10 and 11.

It will be apparent that the arrangement of the securing tongues such asabove described provide for the securing of the brace to the screenframe in a reliable manner so that sagging, warping or derangement ofvthe frame is eliminated owing to the reinforcing action of the anglebrace such as above described.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referredto in the above description, asthe preferred embodiment is the most eilicient and practical; yetrealizing that the conditions concurrent with the adoption of my devicewill necessarily vary, I desire to emphasize the fact that various minorchanges in details of construction, proportion and arrangement of partsmay be resorted to, when required, without sacrilicing any of theadvantages of my invention, as defined in the appended claim.

Having thus described my invention, what is claimed is An angle bracecomprising a metallic body of right angled triangular outline, bottomand side attaching flanges struck up from the body and extending in thesame direction from one face thereof, said flanges being spaced inwardlyfrom and arranged in parallel relation to the bottom and vertical sideedges of the body, respectively, tongues formed by striking the flangesup from the body, said tongues being located in the plane of the Y bodyand outwardly beyond the flanges, and a strut located between two ofsaid tongues and inwardly beyond the flanges, said strut being formed bya portion of the body.

In testimony whereof I allix my signature in presence of two witnesses.

GEORGE H. PIRSON.
